872578 ÷ 8 
The aim is to understand the frequency of 8 in 872578.

On to step 1:
8 divided by 8 is 1 with a remainder of 0.
Use 1 as the next digit of our solution. 
Result so far: 1.0
The remainder is 0 after subtracting 8 from 8.
Append the next digit (7) from the dividend to 0 and continue with: 7 / 8

Advancing to step 2:
8 goes into 7 0 times with a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 10.0
If we subtract 0 from 7, we get 7.
Bring next digit (2) of the dividend behind the 7 and repeat the process: 72 / 8

Let's proceed to step 3:
72 divided by 8 is 9 with a remainder of 0.
The next digit of our result is 9. 
Result so far: 109.0
If we take 72 away from 72, we end up with 0.
Grab the next digit (5) from the dividend, add it to 0, then carry on: 5 / 8

Step 4:
8 goes into 5 0 times with a remainder of 5.
The next digit of our result is 0. 
Result so far: 1090.0
Subtracting 0 from 5 leaves us with 5.
Bring next digit (7) of the dividend behind the 5 and repeat the process: 57 / 8

On to step 5:
8 can be fit into 57 7 times, resulting in a remainder of 1.
The number 7 becomes the next digit in our result. 
Result so far: 10907.0
Subtract 56 from 57 to get 1.
Append the next digit (8) from the dividend to 1 and continue with: 18 / 8

Going ahead to step 6:
18 divided by 8 is 2 with a remainder of 2.
Record the quotient 2 as the next digit in the result. 
Result so far: 109072.0
The remainder is 2 after subtracting 16 from 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Moving on to step 7:
20 divided by 8 is 2 with a remainder of 4.
Write down 2 as next digit of the result. 
Result so far: 109072.2
If we subtract 16 from 20, we get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Going ahead to step 8:
8 goes into 40 5 times with a remainder of 0.
Record the quotient 5 as the next digit in the result. 
Result so far: 109072.25
The remainder is 0 after subtracting 40 from 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Moving on to step 9:
The number 8 fits into 0 0 times, leaving a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 109072.25
If we take 0 away from 0, we end up with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Let's proceed to step 10:
8 goes into 0 0 times with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 109072.25
Deduct 0 from 0 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Our division results in 109072.25 with a remaining 0.0.
